    Multimachine

    Multimachine

    The MultiMachine all-purpose machine tool that can be built by a semi-skilled mechanic with just common hand tools. The necessary material can come from discarded vehicle parts. Using engine blocks as building blocks is the first MultiMachine feature. Since cylinder bores are bored exactly parallel to each other and at exact right angles to the cylinder head surface, MultiMachine accuracy begins at the factory where the engine block was built.

    Poultry Water Heater

    Poultry Water Heater

    A simple, low-cost solution to keep your poultry waterer from freezing. I needed a heater to prevent my chickens' water from freezing and looked at what was available commerically. What I found was just too expensive, around $80.00, so I decided to attempt to make my own. My first attempt was to build a wooden box and place a drop light fixture inside. While functionally this worked, I was concerned about the potential fire hazard of the wooden box so I decided to take another stab using metal. The benefit of using the heat tape is that it comes with an integral thermostat factory set to power on at about 40 degrees and off again at about 45 degrees. By turning the pan upside down I now have a heater that looks remarkably like those expensive commerically available heaters. I set my water container on top and I can tell you it works like a charm! My total cost? $30.00 for new parts and of course there is some value to the miscellaneous stuff I had laying around too, so maybe $35.00 which I consider quite a bargain.

    Electronic Flame Weeder System

    Electronic Flame Weeder System

    This tool is used to allow remote control of a tractor mounted flame weeder. The arduino measures the temperature at the burner, and when no flame is detected sends an ignition spark to the burner. Both the arduino and the solenoid valve are operated by an on/off switch from a 12 volt power supply. The operator turns the burners on at the beginning of the row, and then off at the end of the row. If the wind blows out the flame, the arduino notices this temperature change, and sends a spark to the burner and reignites the propane.

    Pedal Power Hydraulic Log Splitter

    Pedal Power Hydraulic Log Splitter

    Uses pedal power and a hydraulic power unit to split fire wood.

    Row/Bed Marker

    Row/Bed Marker

    The tool shown here is a row/bed marker that is rolled out before direct seeding or transplanting. There are two versions documented - a hand-pushed model and a rear tractor-mounted model. It's purpose is to quickly make a grid that marks row spacing (three rows in this version) as well as your desired in-row spacing (hand-pushed model marks every 4 inches, tractor-mounted model marks every 12 inches). The purpose of this tools to allow one to quickly seed and transplant on a grid for easy cultivation and harvesting. This system also facilitates in keeping track of yields / plants per bed.

    Small DIY Aquaponics System

    Small DIY Aquaponics System

    This is a small aquaponics system I built so I could experiment with the concept. If it works out well for me I'd love to build a large version of this system but before I do want some working knowledge of how it works and any problems i might encounter before I invest a lot of time, effort, and most importantly $$$ into it. This way was a cheap and easy way to gain that knowledge as well as a fun little project. I also want to see what will grow well in the grow bed.

    Underground Rainwater Storage in an IBC with Pumped Supply

    Underground Rainwater Storage in an IBC with Pumped Supply

    Budget pumped rainwater storage. Commercial rainwater storage can be several thousand pounds. To save money I wondered if you could bury an IBC and it turns out you can ! Here's a complete pumped rain water system for about GBP 100.
